Seafood allergies

Foods to avoid

Managing a seafood allergy involves avoiding both obvious and hidden sources of seafood:

  • Fish: Tuna, salmon, cod, halibut, haddock, anchovies, sardines, mackerel, and others.
  • Shellfish
    • Crustaceans: Shrimp, crab, lobster, crayfish.
    • Mollusks: Clams, mussels, oysters, scallops, squid, octopus.

Foods and products that may contain seafood

  • Seafood-based sauces: Fish sauce, oyster sauce, worcestershire sauce (may contain anchovies).
  • Imitation seafood: Surimi (imitation crab), often used in sushi.
  • Processed foods: Certain soups, stews, and broths may use seafood-based stocks.
  • Ethnic foods: Dishes from asian, african, and mediterranean cuisines may use seafood or seafood-based ingredients.
  • Supplements: Some omega-3 supplements are derived from fish oil.

Important: Always read ingredient labels carefully, as seafood can be present in unexpected products.

Suitable alternatives

Incorporate seafood-free foods to maintain a balanced diet:

  • Proteins: Chicken, turkey, beef, pork, eggs, legumes (beans, lentils), tofu, and tempeh.
  • Plant-based seafood alternatives: Products made from soy, wheat, or pea protein designed to mimic the taste and texture of seafood.
  • Omega-3 sources: Flaxseeds, chia seeds, walnuts, and algae-based supplements.

Important: Consult with a registered dietitian to ensure nutritional needs are met while avoiding seafood.

Practical tips

  • Read labels diligently: Ingredients can change, so always check for seafood derivatives.
  • Communicate when dining out: Inform restaurant staff about your allergy to prevent cross-contamination.
  • Educate yourself and others: Understand the various names and forms of seafood to avoid accidental exposure.
  • Carry emergency medication: If prescribed, always have antihistamines or an epinephrine auto-injector on hand.
  • Avoid cross-contamination: Be cautious with shared utensils, cooking surfaces, and bulk bins.
  • Wear medical identification: A medical alert bracelet can provide critical information in emergencies.

Important: Work closely with your healthcare provider to develop a comprehensive allergy management plan.
